Neighbors, teachers, students and friends are coming together to mourn the loss of a Glendale family killed in a devastating house fire this week.

Family members confirm Heather Johnson and her children Tabitha, 14, and twin boys Sean and Jason Gilsinger, 13, died after flames broke out in their home on Mercer Lane.

"We are devastated by the loss of our family members,” the family said in a statement. “We appreciate the love and support we have felt from friends and the community. We ask you to keep our family in your prayers."

Glendale Police said on Thursday the house fire early Wednesday was not suspicious. Investigators are still trying to determine the cause of the fire.
